Now it actually returns the char buffer if available or raises a TypeError if it isn't (as is raised for the other buffer types if they are not present but requested). Not a backport candidate since it does change semantics of the buffer object (although it could be argued this is enough of a bug to bother backporting). ........ r46760 | andrew.kuchling | 2006-06-09 03:10:17 +0200 (Fri, 09 Jun 2006) | 1 line Update functools section ........ r46762 | tim.peters | 2006-06-09 04:11:02 +0200 (Fri, 09 Jun 2006) | 6 lines Whitespace normalization. Since test_file is implicated in mysterious test failures when followed by test_optparse, if I had any brains I'd look at the checkin that last changed test_file ;-) ........ r46763 | tim.peters | 2006-06-09 05:09:42 +0200 (Fri, 09 Jun 2006) | 5 lines To boost morale :-), force test_optparse to run immediately after test_file until we can figure out how to fix it. (See python-dev; at the moment we don't even know which checkin caused the problem.) ........ r46764 | tim.peters | 2006-06-09 05:51:41 +0200 (Fri, 09 Jun 2006) | 6 lines AutoFileTests.tearDown(): Removed mysterious undocumented try/except. Remove TESTFN. Throughout: used open() instead of file(), and wrapped long lines. ........ r46765 | tim.peters | 2006-06-09 06:02:06 +0200 (Fri, 09 Jun 2006) | 8 lines testUnicodeOpen(): I have no idea why, but making this test clean up after itself appears to fix the test failures when test_optparse follows test_file. test_main(): Get rid of TESTFN no matter what. That's also enough to fix the mystery failures. Doesn't hurt to fix them twice :-) ........ r46766 | tim.peters | 2006-06-09 07:12:40 +0200 (Fri, 09 Jun 2006) | 6 lines Remove the temporary hack to force test_optparse to run immediately after test_file. At least 8 buildbot boxes passed since the underlying problem got fixed, and they all failed before the fix, so there's no point to this anymore. ........ r46767 | neal.norwitz | 2006-06-09 07:54:18 +0200 (Fri, 09 Jun 2006) | 1 line Fix grammar and reflow ........ r46769 | andrew.kuchling | 2006-06-09 12:22:35 +0200 (Fri, 09 Jun 2006) | 1 line Markup fix ........ r46773 | andrew.kuchling | 2006-06-09 15:15:57 +0200 (Fri, 09 Jun 2006) | 1 line [Bug #1472827] Make saxutils.XMLGenerator handle \r\n\t in attribute values by escaping them properly. 2.4 bugfix candidate. ........ r46778 | kristjan.jonsson | 2006-06-09 18:28:01 +0200 (Fri, 09 Jun 2006) | 2 lines Turn off warning about deprecated CRT functions on for VisualStudio .NET 2005.

This is the first time in history I don't have a bogus "db_home" directory after running the tests ;-) Also worked on runtest's docstring, to say something about all the arguments, and to document the non-obvious return values. New functions runtest_inner() and cleanup_test_droppings() in support of the above. ........ r46800 | andrew.kuchling | 2006-06-09 21:43:25 +0200 (Fri, 09 Jun 2006) | 1 line Remove unused variable ........ r46801 | andrew.kuchling | 2006-06-09 21:56:05 +0200 (Fri, 09 Jun 2006) | 1 line Add some wsgiref text ........ r46803 | thomas.heller | 2006-06-09 21:59:11 +0200 (Fri, 09 Jun 2006) | 1 line set eol-style svn property ........ r46804 | thomas.heller | 2006-06-09 22:01:01 +0200 (Fri, 09 Jun 2006) | 1 line set eol-style svn property ........ r46805 | georg.brandl | 2006-06-09 22:43:48 +0200 (Fri, 09 Jun 2006) | 3 lines Make use of new str.startswith/endswith semantics.

While this was a real weakness of the older WH generator for lists with just a few dozen elements, and so could potentially bite the naive ;-), the Twister should show excellent behavior up to at least 600 elements.

That appears to be because wsgiref's validate.py uses `assert` statements all over the place to check arguments for sanity. That should all be changed (it's not a logical error in the software if a user passes bogus arguments, so this isn't a reasonable use for `assert` -- checking external preconditions should generally raise ValueError or TypeError instead, as appropriate). ........ r46872 | neal.norwitz | 2006-06-11 23:38:38 +0200 (Sun, 11 Jun 2006) | 1 line Get test to pass on S/390.

As Mark Sapiro rightly points out there are really two types of continued headers defined in this RFC (i.e. "encoded" parameters with the form "name*0*=" and unencoded parameters with the form "name*0="), but we were were handling them both the same way and that isn't correct. This patch should be much more RFC compliant in that only encoded params are %-decoded and the charset/language information is only extract if there are any encoded params in the segments. If there are no encoded params then the RFC says that there will be no charset/language parts. Note however that this will change the return value for Message.get_param() in some cases. For example, whereas before if you had all unencoded param continuations you would have still gotten a 3-tuple back from this method (with charset and language == None), you will now get just a string. I don't believe this is a backward incompatible change though because the documentation for this method already indicates that either return value is possible and that you must do an isinstance(val, tuple) check to discriminate between the two. (Yeah that API kind of sucks but we can't change /that/ without breaking code.)

In general, C doesn't define anything about what happens when an operation on a signed integral type overflows, and PyOS_strtol() did several formally undefined things of that nature on signed longs. Some version of gcc apparently tries to exploit that now, and PyOS_strtol() could fail to detect overflow then. Tried to repair all that, although it seems at least as likely to me that we'll get screwed by bad platform definitions for LONG_MIN and/or LONG_MAX now. For that reason, I don't recommend backporting this. Note that I have no box on which this makes a lick of difference -- can't really test it, except to note that it didn't break anything on my boxes. Silent change: PyOS_strtol() used to return the hard-coded 0x7fffffff in case of overflow. Now it returns LONG_MAX.

Specifically, this allows for querying the type of an object against these built-in C types and more importantly, for getting their docstrings printed in the interactive interpreter's help() function. This patch includes a new built-in module called _types which provides definitions of getset and member descriptors for use by the types.py module. These types are exposed as types.GetSetDescriptorType and types.MemberDescriptorType. Query functions are provided as inspect.isgetsetdescriptor() and inspect.ismemberdescriptor(). The implementations of these are robust enough to work with Python implementations other than CPython, which may not have these fundamental types. The patch also includes documentation and test suite updates. I commit these changes now under these guiding principles: 1. Silence is assent. The release manager has not said "no", and of the few people that cared enough to respond to the thread, the worst vote was "0". 2. It's easier to ask for forgiveness than permission. 3.

I've shrunk the description of 'file' to cross-reference to the 'File objects' section, and to open() for an explanation of the arguments. open() now has all the paragraphs about the mode string. The bufsize argument was moved up so that it isn't buried at the end; now there's 1 paragraph on mode, 1 on bufsize, and then 3 more on mode.

Therefore the same crc can "look negative" on a 32-bit box but "look positive" on a 64-bit box. This patch papers over that platform difference when writing the crc to file. It may be better to change the Python wrapper, either to make the result "look positive" on all platforms (which means it may have to return a Python long at times on a 32-bit box), or to keep the sign the same across boxes. But that would be a visible change in what users see, while the current hack changes no visible behavior (well, apart from stopping the struct deprecation warning).

Several changes: explicitly closed all files; wrapped long lines; stopped suppressing errors when removing a file or directory fails (removing /shouldn't/ fail!); and changed what appeared to be incorrect usage of os.removedirs() (that doesn't remove empty directories at and /under/ the given path, instead it must be given an empty leaf directory and then deletes empty directories moving /up/ the path -- could be that the conceptually simpler shutil.rmtree() was really actually intended here). ........

\section{Debugging Builds \label{debugging}}
|
||||
|
||||
Python can be built with several macros to enable extra checks of the
|
||||
interpreter and extension modules. These checks tend to add a large
|
||||
amount of overhead to the runtime so they are not enabled by default.
|
||||
|
||||
A full list of the various types of debugging builds is in the file
|
||||
\file{Misc/SpecialBuilds.txt} in the Python source distribution.
|
||||
Builds are available that support tracing of reference counts,
|
||||
debugging the memory allocator, or low-level profiling of the main
|
||||
interpreter loop. Only the most frequently-used builds will be
|
||||
described in the remainder of this section.
|
||||
|
||||
Compiling the interpreter with the \csimplemacro{Py_DEBUG} macro
|
||||
defined produces what is generally meant by "a debug build" of Python.
|
||||
\csimplemacro{Py_DEBUG} is enabled in the \UNIX{} build by adding
|
||||
\longprogramopt{with-pydebug} to the \file{configure} command. It is also
|
||||
implied by the presence of the not-Python-specific
|
||||
\csimplemacro{_DEBUG} macro. When \csimplemacro{Py_DEBUG} is enabled
|
||||
in the \UNIX{} build, compiler optimization is disabled.
|
||||
|
||||
In addition to the reference count debugging described below, the
|
||||
following extra checks are performed:
|
||||
|
||||
\begin{itemize}
|
||||
\item Extra checks are added to the object allocator.
|
||||
\item Extra checks are added to the parser and compiler.
|
||||
\item Downcasts from wide types to narrow types are checked for
|
||||
loss of information.
|
||||
\item A number of assertions are added to the dictionary and set
|
||||
implementations. In addition, the set object acquires a
|
||||
\method{test_c_api} method.
|
||||
\item Sanity checks of the input arguments are added to frame
|
||||
creation.
|
||||
\item The storage for long ints is initialized with a known
|
||||
invalid pattern to catch reference to uninitialized
|
||||
digits.
|
||||
\item Low-level tracing and extra exception checking are added
|
||||
to the runtime virtual machine.
|
||||
\item Extra checks are added to the memory arena implementation.
|
||||
\item Extra debugging is added to the thread module.
|
||||
\end{itemize}
|
||||
|
||||
There may be additional checks not mentioned here.
|
||||
|
||||
Defining \csimplemacro{Py_TRACE_REFS} enables reference tracing. When
|
||||
defined, a circular doubly linked list of active objects is maintained
|
||||
by adding two extra fields to every \ctype{PyObject}. Total
|
||||
allocations are tracked as well. Upon exit, all existing references
|
||||
are printed. (In interactive mode this happens after every statement
|
||||
run by the interpreter.) Implied by \csimplemacro{Py_DEBUG}.
|
||||
|
||||
Please refer to \file{Misc/SpecialBuilds.txt} in the Python source
|
||||
distribution for more detailed information.

\subsection{Weak Reference Support\label{weakref-support}}
|
||||
|
||||
One of the goals of Python's weak-reference implementation is to allow
|
||||
any type to participate in the weak reference mechanism without
|
||||
incurring the overhead on those objects which do not benefit by weak
|
||||
referencing (such as numbers).
|
||||
|
||||
For an object to be weakly referencable, the extension must include a
|
||||
\ctype{PyObject*} field in the instance structure for the use of the
|
||||
weak reference mechanism; it must be initialized to \NULL{} by the
|
||||
object's constructor. It must also set the \member{tp_weaklistoffset}
|
||||
field of the corresponding type object to the offset of the field.
|
||||
For example, the instance type is defined with the following
|
||||
structure:
|
||||
|
||||
\begin{verbatim}
|
||||
typedef struct {
|
||||
PyObject_HEAD
|
||||
PyClassObject *in_class; /* The class object */
|
||||
PyObject *in_dict; /* A dictionary */
|
||||
PyObject *in_weakreflist; /* List of weak references */
|
||||
} PyInstanceObject;
|
||||
\end{verbatim}
|
||||
|
||||
The statically-declared type object for instances is defined this way:
|
||||
|
||||
\begin{verbatim}
|
||||
PyTypeObject PyInstance_Type = {
|
||||
PyObject_HEAD_INIT(&PyType_Type)
|
||||
0,
|
||||
"module.instance",
|
||||
|
||||
/* Lots of stuff omitted for brevity... */
|
||||
|
||||
Py_TPFLAGS_DEFAULT, /* tp_flags */
|
||||
0, /* tp_doc */
|
||||
0, /* tp_traverse */
|
||||
0, /* tp_clear */
|
||||
0, /* tp_richcompare */
|
||||
offsetof(PyInstanceObject, in_weakreflist), /* tp_weaklistoffset */
|
||||
};
|
||||
\end{verbatim}
|
||||
|
||||
The type constructor is responsible for initializing the weak reference
|
||||
list to \NULL:
|
||||
|
||||
\begin{verbatim}
|
||||
static PyObject *
|
||||
instance_new() {
|
||||
/* Other initialization stuff omitted for brevity */
|
||||
|
||||
self->in_weakreflist = NULL;
|
||||
|
||||
return (PyObject *) self;
|
||||
}
|
||||
\end{verbatim}
|
||||
|
||||
The only further addition is that the destructor needs to call the
|
||||
weak reference manager to clear any weak references. This should be
|
||||
done before any other parts of the destruction have occurred, but is
|
||||
only required if the weak reference list is non-\NULL:
|
||||
|
||||
\begin{verbatim}
|
||||
static void
|
||||
instance_dealloc(PyInstanceObject *inst)
|
||||
{
|
||||
/* Allocate temporaries if needed, but do not begin
|
||||
destruction just yet.
|
||||
*/
|
||||
|
||||
if (inst->in_weakreflist != NULL)
|
||||
PyObject_ClearWeakRefs((PyObject *) inst);

\begin{funcdesc}{byref}{obj}
|

Returns a light-weight pointer to \var{obj}, which must be an instance
|

of a ctypes type. The returned object can only be used as a foreign
|

\end{funcdesc}
|

\begin{funcdesc}{CFUNCTYPE}{restype, *argtypes}
|
||||
This is a factory function that returns a function prototype. The
|
||||
function prototype describes a function that has a result type of
|
||||
\code{restype}, and accepts arguments as specified by \code{argtypes}.
|
||||
The function prototype can be used to construct several kinds of
|
||||
functions, depending on how the prototype is called.
|
||||
|
||||
The prototypes returned by \code{CFUNCTYPE} or \code{PYFUNCTYPE}
|
||||
create functions that use the standard C calling convention,
|

prototypes returned from \code{WINFUNCTYPE} (on Windows) use the

\code{__stdcall} calling convention.
|

|

Functions created by calling the \code{CFUNCTYPE} and
|

\code{WINFUNCTYPE} prototypes release the Python GIL
|
||||
before entering the foreign function, and acquire it back after

leaving the function code.

\begin{funcdesc}{create_string_buffer}{init_or_size\optional{, size}}
|
||||
This function creates a mutable character buffer. The returned object
|
||||
is a ctypes array of \code{c_char}.
|
||||
|
||||
\var{init_or_size} must be an integer which specifies the size of the
|
||||
array, or a string which will be used to initialize the array items.
|
||||
|
||||
If a string is specified as first argument, the buffer is made one
|
||||
item larger than the length of the string so that the last element in
|
||||
the array is a NUL termination character. An integer can be passed as
|
||||
second argument which allows to specify the size of the array if the
|
||||
length of the string should not be used.
|
||||
|
||||
If the first parameter is a unicode string, it is converted into an
|
||||
8-bit string according to ctypes conversion rules.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{create_unicode_buffer}{init_or_size\optional{, size}}
|
||||
This function creates a mutable unicode character buffer. The

returned object is a ctypes array of \code{c_wchar}.
|
||||
|
||||
\var{init_or_size} must be an integer which specifies the size of the
|
||||
array, or a unicode string which will be used to initialize the array
|
||||
items.
|
||||
|
||||
If a unicode string is specified as first argument, the buffer is made
|
||||
one item larger than the length of the string so that the last element
|
||||
in the array is a NUL termination character. An integer can be passed
|
||||
as second argument which allows to specify the size of the array if
|
||||
the length of the string should not be used.
|
||||
|
||||
If the first parameter is a 8-bit string, it is converted into an

\begin{funcdesc}{FormatError}{\optional{code}}
|

\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{memmove}{dst, src, count}
|
||||
Same as the standard C \code{memmove} library function: copies
|
||||
\var{count} bytes from \code{src} to \code{dst}. \code{dst} and
|
||||
\code{src} must be integers or ctypes instances that can be converted to pointers.
|

\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{memset}{dst, c, count}
|
||||
Same as the standard C \code{memset} library function: fills the
|

memory clock at address \code{dst} with \var{count} bytes of value
|
||||
\var{c}. \var{dst} must be an integer specifying an address, or a ctypes instance.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{POINTER}{type}
|
||||
This factory function creates and returns a new ctypes pointer type.
|
||||
Pointer types are cached an reused internally, so calling this
|
||||
function repeatedly is cheap. \var{type} must be a ctypes type.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{pointer}{obj}
|
||||
This function creates a new pointer instance, pointing to \var{obj}.
|

The returned object is of the type \code{POINTER(type(obj))}.
|
||||
|
||||
Note: If you just want to pass a pointer to an object to a foreign
|
||||
function call, you should use \code{byref(obj)} which is much faster.

\end{funcdesc}
|

|
||||
\begin{funcdesc}{resize}{obj, size}
|
||||
This function resizes the internal memory buffer of \var{obj}, which
|
||||
must be an instance of a ctypes type. It is not possible to make the
|
||||
buffer smaller than the native size of the objects type, as given by
|
||||
\code{sizeof(type(obj))}, but it is possible to enlarge the buffer.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{set_conversion_mode}{encoding, errors}
|
||||
This function sets the rules that ctypes objects use when converting
|
||||
between 8-bit strings and unicode strings. \var{encoding} must be a
|
||||
string specifying an encoding, like 'utf-8' or 'mbcs', \var{errors}
|
||||
must be a string specifying the error handling on encoding/decoding
|
||||
errors. Examples of possible values are ``strict'', ``replace'', or
|
||||
``ignore''.
|
||||
|
||||
\code{set_conversion_mode} returns a 2-tuple containing the previous
|
||||
conversion rules. On windows, the initial conversion rules are
|
||||
\code{('mbcs', 'ignore')}, on other systems \code{('ascii', 'strict')}.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{sizeof}{obj_or_type}
|
||||
Returns the size in bytes of a ctypes type or instance memory buffer.
|
||||
Does the same as the C sizeof() function.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{string_at}{address\optional{size}}
|
||||
This function returns the string starting at memory address
|
||||
\var{address}. If \var{size} is specified, it is used as size,
|
||||
otherwise the string is assumed to be zero-terminated.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{WinError}{code=None, descr=None}
|
||||
Windows only: this function is probably the worst-named thing in
|
||||
ctypes. It creates an instance of \code{WindowsError}. If \var{code}
|
||||
is not specified, \code{GetLastError} is called to determine the error
|
||||
code. If \var{descr} is not spcified, \var{FormatError} is called to
|
||||
get a textual description of the error.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{WINFUNCTYPE}{restype, *argtypes}
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{wstring_at}{address}
|
||||
This function returns the wide character string starting at memory
|
||||
address \var{address} as unicode string. If \var{size} is specified,
|
||||
it is used as size, otherwise the string is assumed to be
|
||||
zero-terminated.

\moduleauthor{Fredrik Lundh}{fredrik@pythonware.com}
|
||||
\modulesynopsis{This module provides implementations
|
||||
of the Element and ElementTree types, plus support classes.
|
||||
|
||||
A C version of this API is available as xml.etree.cElementTree.}
|
||||
\versionadded{2.5}
|
||||
|
||||
|
||||
\subsection{Overview\label{elementtree-overview}}
|
||||
|
||||
The Element type is a flexible container object, designed to store
|
||||
hierarchical data structures in memory. The type can be described as a
|
||||
cross between a list and a dictionary.
|
||||
|
||||
Each element has a number of properties associated with it:
|
||||
\begin{itemize}
|
||||
\item {}
|
||||
a tag which is a string identifying what kind of data
|
||||
this element represents (the element type, in other words).
|
||||
|
||||
\item {}
|
||||
a number of attributes, stored in a Python dictionary.
|
||||
|
||||
\item {}
|
||||
a text string.
|
||||
|
||||
\item {}
|
||||
an optional tail string.
|
||||
|
||||
\item {}
|
||||
a number of child elements, stored in a Python sequence
|
||||
|
||||
\end{itemize}
|
||||
|
||||
To create an element instance, use the Element or SubElement factory
|
||||
functions.
|
||||
|
||||
The ElementTree class can be used to wrap an element
|
||||
structure, and convert it from and to XML.
|
||||
|
||||
|
||||
\subsection{Functions\label{elementtree-functions}}
|
||||
|
||||
\begin{funcdesc}{Comment}{\optional{text}}
|
||||
Comment element factory. This factory function creates a special
|
||||
element that will be serialized as an XML comment.

|

Return a new file object (described in
|
||||
section~\ref{bltin-file-objects}, ``\ulink{File
|
||||
Objects}{bltin-file-objects.html}'').
|
||||
The first two arguments are the same as for \code{stdio}'s
|
||||
\cfunction{fopen()}: \var{filename} is the file name to be opened,
|
||||
\var{mode} indicates how the file is to be opened: \code{'r'} for
|
||||
reading, \code{'w'} for writing (truncating an existing file), and
|
||||
\code{'a'} opens it for appending (which on \emph{some} \UNIX{}
|
||||
systems means that \emph{all} writes append to the end of the file,
|
||||
regardless of the current seek position).
|
||||
Constructor function for the \class{file} type, described further
|
||||
in section~\ref{bltin-file-objects}, ``\ulink{File
|
||||
Objects}{bltin-file-objects.html}''. The constructor's arguments
|
||||
are the same as those of the \function{open()} built-in function
|
||||
described below.
|
||||
|
||||
Modes \code{'r+'}, \code{'w+'} and \code{'a+'} open the file for
|
||||
updating (note that \code{'w+'} truncates the file). Append
|
||||
\code{'b'} to the mode to open the file in binary mode, on systems
|
||||
that differentiate between binary and text files (else it is
|
||||
ignored). If the file cannot be opened, \exception{IOError} is
|
||||
raised.
|
||||
|
||||
In addition to the standard \cfunction{fopen()} values \var{mode}
|
||||
may be \code{'U'} or \code{'rU'}. If Python is built with universal
|
||||
newline support (the default) the file is opened as a text file, but
|
||||
lines may be terminated by any of \code{'\e n'}, the Unix end-of-line
|
||||
convention,
|
||||
\code{'\e r'}, the Macintosh convention or \code{'\e r\e n'}, the Windows
|
||||
convention. All of these external representations are seen as
|
||||
\code{'\e n'}
|
||||
by the Python program. If Python is built without universal newline support
|
||||
\var{mode} \code{'U'} is the same as normal text mode. Note that
|
||||
file objects so opened also have an attribute called
|
||||
\member{newlines} which has a value of \code{None} (if no newlines
|
||||
have yet been seen), \code{'\e n'}, \code{'\e r'}, \code{'\e r\e n'},
|
||||
or a tuple containing all the newline types seen.
|
||||
|
||||
Python enforces that the mode, after stripping \code{'U'}, begins with
|
||||
\code{'r'}, \code{'w'} or \code{'a'}.
|
||||
|
||||
If \var{mode} is omitted, it defaults to \code{'r'}. When opening a
|
||||
binary file, you should append \code{'b'} to the \var{mode} value
|
||||
for improved portability. (It's useful even on systems which don't
|
||||
treat binary and text files differently, where it serves as
|
||||
documentation.)

A wrapper for the \function{file()} function above. The intent is

for \function{open()} to be preferred for use as a factory function

returning a new \class{file} object. \class{file} is more suited to

Open a file, returning an object of the \class{file} type described
|

in section~\ref{bltin-file-objects}, ``\ulink{File
|
||||
Objects}{bltin-file-objects.html}''. If the file cannot be opened,
|
||||
\exception{IOError} is raised. When opening a file, it's
|
||||
preferable to use \function{open()} instead of invoking the
|
||||
\class{file} constructor directly.
|
||||
|
||||
The first two arguments are the same as for \code{stdio}'s
|
||||
\cfunction{fopen()}: \var{filename} is the file name to be opened,
|
||||
and \var{mode} is a string indicating how the file is to be opened.
|
||||
|
||||
The most commonly-used values of \var{mode} are \code{'r'} for
|
||||
reading, \code{'w'} for writing (truncating the file if it already
|
||||
exists), and \code{'a'} for appending (which on \emph{some} \UNIX{}
|
||||
systems means that \emph{all} writes append to the end of the file
|
||||
regardless of the current seek position). If \var{mode} is omitted,
|
||||
it defaults to \code{'r'}. When opening a binary file, you should
|
||||
append \code{'b'} to the \var{mode} value to open the file in binary
|
||||
mode, which will improve portability. (Appending \code{'b'} is
|
||||
useful even on systems that don't treat binary and text files
|
||||
differently, where it serves as documentation.) See below for more

possible values of \var{mode}.

The optional \var{bufsize} argument specifies the
|
||||
file's desired buffer size: 0 means unbuffered, 1 means line
|
||||
buffered, any other positive value means use a buffer of
|
||||
(approximately) that size. A negative \var{bufsize} means to use

the system default, which is usually line buffered for tty

|
||||
|
||||
Modes \code{'r+'}, \code{'w+'} and \code{'a+'} open the file for
|
||||
updating (note that \code{'w+'} truncates the file). Append
|
||||
\code{'b'} to the mode to open the file in binary mode, on systems
|
||||
that differentiate between binary and text files; on systems
|
||||
that don't have this distinction, adding the \code{'b'} has no effect.
|
||||
|
||||
In addition to the standard \cfunction{fopen()} values \var{mode}
|
||||
may be \code{'U'} or \code{'rU'}. Python is usually built with universal
|
||||
newline support; supplying \code{'U'} opens the file as a text file, but
|
||||
lines may be terminated by any of the following: the \UNIX{} end-of-line
|
||||
convention \code{'\e n'},
|
||||
the Macintosh convention \code{'\e r'}, or the Windows
|
||||
convention \code{'\e r\e n'}. All of these external representations are seen as
|
||||
\code{'\e n'}
|
||||
by the Python program. If Python is built without universal newline support
|
||||
a \var{mode} with \code{'U'} is the same as normal text mode. Note that
|
||||
file objects so opened also have an attribute called
|
||||
\member{newlines} which has a value of \code{None} (if no newlines
|
||||
have yet been seen), \code{'\e n'}, \code{'\e r'}, \code{'\e r\e n'},
|
||||
or a tuple containing all the newline types seen.
|
||||
|
||||
Python enforces that the mode, after stripping \code{'U'}, begins with
|
||||
\code{'r'}, \code{'w'} or \code{'a'}.

\subsection{Extending \module{optparse}\label{optparse-extending-optparse}}
|
||||
|
||||
Since the two major controlling factors in how \module{optparse} interprets
|
||||
command-line options are the action and type of each option, the most
|
||||
likely direction of extension is to add new actions and new types.
|
||||
|
||||
|
||||
\subsubsection{Adding new types\label{optparse-adding-new-types}}
|
||||
|
||||
To add new types, you need to define your own subclass of \module{optparse}'s Option
|
||||
class. This class has a couple of attributes that define \module{optparse}'s types:
|
||||
\member{TYPES} and \member{TYPE{\_}CHECKER}.
|
||||
|
||||
\member{TYPES} is a tuple of type names; in your subclass, simply define a new
|
||||
tuple \member{TYPES} that builds on the standard one.
|
||||
|
||||
\member{TYPE{\_}CHECKER} is a dictionary mapping type names to type-checking
|
||||
functions. A type-checking function has the following signature:
|
||||
\begin{verbatim}
|
||||
def check_mytype(option, opt, value)
|
||||
\end{verbatim}
|
||||
|
||||
where \code{option} is an \class{Option} instance, \code{opt} is an option string
|
||||
(e.g., \code{"-f"}), and \code{value} is the string from the command line that
|
||||
must be checked and converted to your desired type. \code{check{\_}mytype()}
|
||||
should return an object of the hypothetical type \code{mytype}. The value
|
||||
returned by a type-checking function will wind up in the OptionValues
|
||||
instance returned by \method{OptionParser.parse{\_}args()}, or be passed to a
|
||||
callback as the \code{value} parameter.
|
||||
|
||||
Your type-checking function should raise OptionValueError if it
|
||||
encounters any problems. OptionValueError takes a single string
|
||||
argument, which is passed as-is to OptionParser's \method{error()} method,
|
||||
which in turn prepends the program name and the string \code{"error:"} and
|
||||
prints everything to stderr before terminating the process.
|
||||
|
||||
Here's a silly example that demonstrates adding a \code{complex} option
|
||||
type to parse Python-style complex numbers on the command line. (This
|
||||
is even sillier than it used to be, because \module{optparse} 1.3 added built-in
|
||||
support for complex numbers, but never mind.)
|
||||
|
||||
First, the necessary imports:
|
||||
\begin{verbatim}
|
||||
from copy import copy
|
||||
from optparse import Option, OptionValueError
|
||||
\end{verbatim}
|
||||
|
||||
You need to define your type-checker first, since it's referred to later
|
||||
(in the \member{TYPE{\_}CHECKER} class attribute of your Option subclass):
|
||||
\begin{verbatim}
|
||||
def check_complex(option, opt, value):
|
||||
try:
|
||||
return complex(value)
|
||||
except ValueError:
|
||||
raise OptionValueError(
|
||||
"option %s: invalid complex value: %r" % (opt, value))
|
||||
\end{verbatim}
|
||||
|
||||
Finally, the Option subclass:
|
||||
\begin{verbatim}
|
||||
class MyOption (Option):
|
||||
TYPES = Option.TYPES + ("complex",)
|
||||
TYPE_CHECKER = copy(Option.TYPE_CHECKER)
|
||||
TYPE_CHECKER["complex"] = check_complex
|
||||
\end{verbatim}
|
||||
|
||||
(If we didn't make a \function{copy()} of \member{Option.TYPE{\_}CHECKER}, we would end
|
||||
up modifying the \member{TYPE{\_}CHECKER} attribute of \module{optparse}'s Option class.
|
||||
This being Python, nothing stops you from doing that except good manners
|
||||
and common sense.)
|
||||
|
||||
That's it! Now you can write a script that uses the new option type
|
||||
just like any other \module{optparse}-based script, except you have to instruct your
|
||||
OptionParser to use MyOption instead of Option:
|
||||
\begin{verbatim}
|
||||
parser = OptionParser(option_class=MyOption)
|
||||
parser.add_option("-c", type="complex")
|
||||
\end{verbatim}
|
||||
|
||||
Alternately, you can build your own option list and pass it to
|
||||
OptionParser; if you don't use \method{add{\_}option()} in the above way, you
|
||||
don't need to tell OptionParser which option class to use:
|
||||
\begin{verbatim}
|
||||
option_list = [MyOption("-c", action="store", type="complex", dest="c")]
|
||||
parser = OptionParser(option_list=option_list)
|
||||
\end{verbatim}
|
||||
|
||||
|
||||
\subsubsection{Adding new actions\label{optparse-adding-new-actions}}
|
||||
|
||||
Adding new actions is a bit trickier, because you have to understand
|
||||
that \module{optparse} has a couple of classifications for actions:
|
||||
\begin{description}
|
||||
\item[``store'' actions]
|
||||
actions that result in \module{optparse} storing a value to an attribute of the
|
||||
current OptionValues instance; these options require a \member{dest}
|
||||
attribute to be supplied to the Option constructor
|
||||
\item[``typed'' actions]
|
||||
actions that take a value from the command line and expect it to be
|
||||
of a certain type; or rather, a string that can be converted to a
|
||||
certain type. These options require a \member{type} attribute to the
|
||||
Option constructor.
|
||||
\end{description}
|
||||
|
||||
These are overlapping sets: some default ``store'' actions are \code{store},
|
||||
\code{store{\_}const}, \code{append}, and \code{count}, while the default ``typed''
|
||||
actions are \code{store}, \code{append}, and \code{callback}.
|
||||
|
||||
When you add an action, you need to categorize it by listing it in at
|
||||
least one of the following class attributes of Option (all are lists of
|
||||
strings):
|
||||
\begin{description}
|
||||
\item[\member{ACTIONS}]
|
||||
all actions must be listed in ACTIONS
|
||||
\item[\member{STORE{\_}ACTIONS}]
|
||||
``store'' actions are additionally listed here
|
||||
\item[\member{TYPED{\_}ACTIONS}]
|
||||
``typed'' actions are additionally listed here
|
||||
\item[\code{ALWAYS{\_}TYPED{\_}ACTIONS}]
|
||||
actions that always take a type (i.e. whose options always take a
|
||||
value) are additionally listed here. The only effect of this is
|
||||
that \module{optparse} assigns the default type, \code{string}, to options with no
|
||||
explicit type whose action is listed in \code{ALWAYS{\_}TYPED{\_}ACTIONS}.
|
||||
\end{description}
|
||||
|
||||
In order to actually implement your new action, you must override
|
||||
Option's \method{take{\_}action()} method and add a case that recognizes your
|
||||
action.
|
||||
|
||||
For example, let's add an \code{extend} action. This is similar to the
|
||||
standard \code{append} action, but instead of taking a single value from
|
||||
the command-line and appending it to an existing list, \code{extend} will
|
||||
take multiple values in a single comma-delimited string, and extend an
|
||||
existing list with them. That is, if \code{"-{}-names"} is an \code{extend}
|
||||
option of type \code{string}, the command line
|
||||
\begin{verbatim}
|
||||
--names=foo,bar --names blah --names ding,dong
|
||||
\end{verbatim}
|
||||
|
||||
would result in a list
|
||||
\begin{verbatim}
|
||||
["foo", "bar", "blah", "ding", "dong"]
|
||||
\end{verbatim}
|
||||
|
||||
Again we define a subclass of Option:
|
||||
\begin{verbatim}
|
||||
class MyOption (Option):
|
||||
|
||||
ACTIONS = Option.ACTIONS + ("extend",)
|
||||
STORE_ACTIONS = Option.STORE_ACTIONS + ("extend",)
|
||||
TYPED_ACTIONS = Option.TYPED_ACTIONS + ("extend",)
|
||||
ALWAYS_TYPED_ACTIONS = Option.ALWAYS_TYPED_ACTIONS + ("extend",)
|
||||
|
||||
def take_action(self, action, dest, opt, value, values, parser):
|
||||
if action == "extend":
|
||||
lvalue = value.split(",")
|
||||
values.ensure_value(dest, []).extend(lvalue)
|
||||
else:
|
||||
Option.take_action(
|
||||
self, action, dest, opt, value, values, parser)
|
||||
\end{verbatim}
|
||||
|
||||
Features of note:
|
||||
\begin{itemize}
|
||||
\item {}
|
||||
\code{extend} both expects a value on the command-line and stores that
|
||||
value somewhere, so it goes in both \member{STORE{\_}ACTIONS} and
|
||||
\member{TYPED{\_}ACTIONS}
|
||||
|
||||
\item {}
|
||||
to ensure that \module{optparse} assigns the default type of \code{string} to
|
||||
\code{extend} actions, we put the \code{extend} action in
|
||||
\code{ALWAYS{\_}TYPED{\_}ACTIONS} as well
|
||||
|
||||
\item {}
|
||||
\method{MyOption.take{\_}action()} implements just this one new action, and
|
||||
passes control back to \method{Option.take{\_}action()} for the standard
|
||||
\module{optparse} actions
|
||||
|
||||
\item {}
|
||||
\code{values} is an instance of the optparse{\_}parser.Values class,
|
||||
which provides the very useful \method{ensure{\_}value()} method.
|
||||
\method{ensure{\_}value()} is essentially \function{getattr()} with a safety valve;
|
||||
it is called as
|
||||
\begin{verbatim}
|
||||
values.ensure_value(attr, value)
|
||||
\end{verbatim}
|
||||
|
||||
If the \code{attr} attribute of \code{values} doesn't exist or is None, then
|
||||
ensure{\_}value() first sets it to \code{value}, and then returns 'value.
|
||||
This is very handy for actions like \code{extend}, \code{append}, and
|
||||
\code{count}, all of which accumulate data in a variable and expect that
|
||||
variable to be of a certain type (a list for the first two, an integer
|
||||
for the latter). Using \method{ensure{\_}value()} means that scripts using
|
||||
your action don't have to worry about setting a default value for the
|
||||
option destinations in question; they can just leave the default as
|
||||
None and \method{ensure{\_}value()} will take care of getting it right when
|
||||
it's needed.

For the simplest code, use the \function{dump()} and \function{load()}

subsequently created threads, and must be 0 (use platform or

restrictions on values for the stack size, such as requiring a minimum

This module provides immutable \class{UUID} objects (the \class{UUID} class)
|
||||
and the functions \function{uuid1()}, \function{uuid3()},
|
||||
\function{uuid4()}, \function{uuid5()} for generating version 1, 3, 4,
|
||||
and 5 UUIDs as specified in \rfc{4122}.
|
||||
|
||||
If all you want is a unique ID, you should probably call
|
||||
\function{uuid1()} or \function{uuid4()}. Note that \function{uuid1()}
|
||||
may compromise privacy since it creates a UUID containing the computer's
|
||||
network address. \function{uuid4()} creates a random UUID.
|
||||
|
||||
\begin{classdesc}{UUID}{\optional{hex\optional{, bytes\optional{,
|
||||
fields\optional{, int\optional{, version}}}}}}
|
||||
|
||||
%Instances of the UUID class represent UUIDs as specified in RFC 4122.
|
||||
%UUID objects are immutable, hashable, and usable as dictionary keys.
|
||||
%Converting a UUID to a string with str() yields something in the form
|
||||
%'12345678-1234-1234-1234-123456789abc'. The UUID constructor accepts
|
||||
%four possible forms: a similar string of hexadecimal digits, or a
|
||||
%string of 16 raw bytes as an argument named 'bytes', or a tuple of
|
||||
%six integer fields (with 32-bit, 16-bit, 16-bit, 8-bit, 8-bit, and
|
||||
%48-bit values respectively) as an argument named 'fields', or a single
|
||||
%128-bit integer as an argument named 'int'.
|
||||
|
||||
Create a UUID from either a string of 32 hexadecimal digits,
|
||||
a string of 16 bytes as the \var{bytes} argument, a tuple of six
|
||||
integers (32-bit \var{time_low}, 16-bit \var{time_mid},
|
||||
16-bit \var{time_hi_version},
|
||||
8-bit \var{clock_seq_hi_variant}, 8-bit \var{clock_seq_low}, 48-bit \var{node})
|
||||
as the \var{fields} argument, or a single 128-bit integer as the \var{int}
|
||||
argument. When a string of hex digits is given, curly braces,
|
||||
hyphens, and a URN prefix are all optional. For example, these
|
||||
expressions all yield the same UUID:
|
||||
|
||||
\begin{verbatim}
|
||||
UUID('{12345678-1234-5678-1234-567812345678}')
|
||||

|
||||

|
||||
\end{verbatim}
|
||||
|
||||
Exactly one of \var{hex}, \var{bytes}, \var{fields}, or \var{int} must
|
||||
be given. The \var{version} argument is optional; if given, the
|
||||
resulting UUID will have its variant and version number set according to
|
||||
RFC 4122, overriding bits in the given \var{hex}, \var{bytes},
|
||||
\var{fields}, or \var{int}.

\subsection{Weak References in Extension Types
|
||||
\label{weakref-extension}}
|
||||
|
||||
One of the goals of the implementation is to allow any type to
|
||||
participate in the weak reference mechanism without incurring the
|
||||
overhead on those objects which do not benefit by weak referencing
|
||||
(such as numbers).
|
||||
|
||||
For an object to be weakly referencable, the extension must include a
|
||||
\ctype{PyObject*} field in the instance structure for the use of the
|
||||
weak reference mechanism; it must be initialized to \NULL{} by the
|
||||
object's constructor. It must also set the \member{tp_weaklistoffset}
|
||||
field of the corresponding type object to the offset of the field.
|
||||
Also, it needs to add \constant{Py_TPFLAGS_HAVE_WEAKREFS} to the
|
||||
tp_flags slot. For example, the instance type is defined with the
|
||||
following structure:
|
||||
|
||||
\begin{verbatim}
|
||||
typedef struct {
|
||||
PyObject_HEAD
|
||||
PyClassObject *in_class; /* The class object */
|
||||
PyObject *in_dict; /* A dictionary */
|
||||
PyObject *in_weakreflist; /* List of weak references */
|
||||
} PyInstanceObject;
|
||||
\end{verbatim}
|
||||
|
||||
The statically-declared type object for instances is defined this way:
|
||||
|
||||
\begin{verbatim}
|
||||
PyTypeObject PyInstance_Type = {
|
||||
PyObject_HEAD_INIT(&PyType_Type)
|
||||
0,
|
||||
"module.instance",
|
||||
|
||||
/* Lots of stuff omitted for brevity... */
|
||||
|
||||
Py_TPFLAGS_DEFAULT | Py_TPFLAGS_HAVE_WEAKREFS /* tp_flags */
|
||||
0, /* tp_doc */
|
||||
0, /* tp_traverse */
|
||||
0, /* tp_clear */
|
||||
0, /* tp_richcompare */
|
||||
offsetof(PyInstanceObject, in_weakreflist), /* tp_weaklistoffset */
|
||||
};
|
||||
\end{verbatim}
|
||||
|
||||
The type constructor is responsible for initializing the weak reference
|
||||
list to \NULL:
|
||||
|
||||
\begin{verbatim}
|
||||
static PyObject *
|
||||
instance_new() {
|
||||
/* Other initialization stuff omitted for brevity */
|
||||
|
||||
self->in_weakreflist = NULL;
|
||||
|
||||
return (PyObject *) self;
|
||||
}
|
||||
\end{verbatim}
|
||||
|
||||
The only further addition is that the destructor needs to call the
|
||||
weak reference manager to clear any weak references. This should be
|
||||
done before any other parts of the destruction have occurred, but is
|
||||
only required if the weak reference list is non-\NULL:
|
||||
|
||||
\begin{verbatim}
|
||||
static void
|
||||
instance_dealloc(PyInstanceObject *inst)
|
||||
{
|
||||
/* Allocate temporaries if needed, but do not begin
|
||||
destruction just yet.
|
||||
*/
|
||||
|
||||
if (inst->in_weakreflist != NULL)
|
||||
PyObject_ClearWeakRefs((PyObject *) inst);
|
||||
|
||||
/* Proceed with object destruction normally. */

||||

\versionadded{2.5}
|
||||
|
||||
The Web Server Gateway Interface (WSGI) is a standard interface
|
||||
between web server software and web applications written in Python.
|
||||
Having a standard interface makes it easy to use an application
|
||||
that supports WSGI with a number of different web servers.
|
||||
|
||||
Only authors of web servers and programming frameworks need to know
|
||||
every detail and corner case of the WSGI design. You don't need to
|
||||
understand every detail of WSGI just to install a WSGI application or
|
||||
to write a web application using an existing framework.
|
||||
|
||||
\module{wsgiref} is a reference implementation of the WSGI specification
|
||||
that can be used to add WSGI support to a web server or framework. It
|
||||
provides utilities for manipulating WSGI environment variables and
|
||||
response headers, base classes for implementing WSGI servers, a demo
|
||||
HTTP server that serves WSGI applications, and a validation tool that
|
||||
checks WSGI servers and applications for conformance to the
|
||||
WSGI specification (\pep{333}).

||||

\subsection{\module{wsgiref.util} -- WSGI environment utilities}
|
||||
\declaremodule{}{wsgiref.util}
|
||||
|
||||
This module provides a variety of utility functions for working with
|
||||
WSGI environments. A WSGI environment is a dictionary containing
|
||||
HTTP request variables as described in \pep{333}. All of the functions
|
||||
taking an \var{environ} parameter expect a WSGI-compliant dictionary to
|
||||
be supplied; please see \pep{333} for a detailed specification.
|
||||
|
||||
\begin{funcdesc}{guess_scheme}{environ}
|
||||
Return a guess for whether \code{wsgi.url_scheme} should be ``http'' or
|
||||
``https'', by checking for a \code{HTTPS} environment variable in the
|
||||
\var{environ} dictionary. The return value is a string.
|
||||
|
||||
This function is useful when creating a gateway that wraps CGI or a
|
||||
CGI-like protocol such as FastCGI. Typically, servers providing such
|
||||
protocols will include a \code{HTTPS} variable with a value of ``1''
|
||||
``yes'', or ``on'' when a request is received via SSL. So, this
|
||||
function returns ``https'' if such a value is found, and ``http''
|
||||
otherwise.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{request_uri}{environ \optional{, include_query=1}}
|
||||
Return the full request URI, optionally including the query string,
|
||||
using the algorithm found in the ``URL Reconstruction'' section of
|
||||
\pep{333}. If \var{include_query} is false, the query string is
|
||||
not included in the resulting URI.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{application_uri}{environ}
|
||||
Similar to \function{request_uri}, except that the \code{PATH_INFO} and
|
||||
\code{QUERY_STRING} variables are ignored. The result is the base URI
|
||||
of the application object addressed by the request.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{shift_path_info}{environ}
|
||||
Shift a single name from \code{PATH_INFO} to \code{SCRIPT_NAME} and
|
||||
return the name. The \var{environ} dictionary is \emph{modified}
|
||||
in-place; use a copy if you need to keep the original \code{PATH_INFO}
|
||||
or \code{SCRIPT_NAME} intact.
|
||||
|
||||
If there are no remaining path segments in \code{PATH_INFO}, \code{None}
|
||||
is returned.
|
||||
|
||||
Typically, this routine is used to process each portion of a request
|
||||
URI path, for example to treat the path as a series of dictionary keys.
|
||||
This routine modifies the passed-in environment to make it suitable for
|
||||
invoking another WSGI application that is located at the target URI.
|
||||
For example, if there is a WSGI application at \code{/foo}, and the
|
||||
request URI path is \code{/foo/bar/baz}, and the WSGI application at
|
||||
\code{/foo} calls \function{shift_path_info}, it will receive the string
|
||||
``bar'', and the environment will be updated to be suitable for passing
|
||||
to a WSGI application at \code{/foo/bar}. That is, \code{SCRIPT_NAME}
|
||||
will change from \code{/foo} to \code{/foo/bar}, and \code{PATH_INFO}
|
||||
will change from \code{/bar/baz} to \code{/baz}.
|
||||
|
||||
When \code{PATH_INFO} is just a ``/'', this routine returns an empty
|
||||
string and appends a trailing slash to \code{SCRIPT_NAME}, even though
|
||||
empty path segments are normally ignored, and \code{SCRIPT_NAME} doesn't
|
||||
normally end in a slash. This is intentional behavior, to ensure that
|
||||
an application can tell the difference between URIs ending in \code{/x}
|
||||
from ones ending in \code{/x/} when using this routine to do object
|
||||
traversal.
|
||||
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{funcdesc}{setup_testing_defaults}{environ}
|
||||
Update \var{environ} with trivial defaults for testing purposes.
|
||||
|
||||
This routine adds various parameters required for WSGI, including
|
||||
\code{HTTP_HOST}, \code{SERVER_NAME}, \code{SERVER_PORT},
|
||||
\code{REQUEST_METHOD}, \code{SCRIPT_NAME}, \code{PATH_INFO}, and all of
|
||||
the \pep{333}-defined \code{wsgi.*} variables. It only supplies default
|
||||
values, and does not replace any existing settings for these variables.
|
||||
|
||||
This routine is intended to make it easier for unit tests of WSGI
|
||||
servers and applications to set up dummy environments. It should NOT
|
||||
be used by actual WSGI servers or applications, since the data is fake!
|
||||
\end{funcdesc}
|
||||
|
||||
|
||||
|
||||
In addition to the environment functions above, the
|
||||
\module{wsgiref.util} module also provides these miscellaneous
|
||||
utilities:
|
||||
|
||||
\begin{funcdesc}{is_hop_by_hop}{header_name}
|
||||
Return true if 'header_name' is an HTTP/1.1 ``Hop-by-Hop'' header, as
|
||||
defined by \rfc{2616}.
|
||||
\end{funcdesc}
|
||||
|
||||
\begin{classdesc}{FileWrapper}{filelike \optional{, blksize=8192}}
|
||||
A wrapper to convert a file-like object to an iterator. The resulting
|
||||
objects support both \method{__getitem__} and \method{__iter__}
|
||||
iteration styles, for compatibility with Python 2.1 and Jython.
|
||||
As the object is iterated over, the optional \var{blksize} parameter
|
||||
will be repeatedly passed to the \var{filelike} object's \method{read()}
|
||||
method to obtain strings to yield. When \method{read()} returns an
|
||||
empty string, iteration is ended and is not resumable.
|
||||
|
||||
If \var{filelike} has a \method{close()} method, the returned object
|
||||
will also have a \method{close()} method, and it will invoke the
|
||||
\var{filelike} object's \method{close()} method when called.
|
||||
\end{classdesc}

||||

\subsection{\module{wsgiref.headers} -- WSGI response header tools}
|
||||
\declaremodule{}{wsgiref.headers}
|
||||
|
||||
This module provides a single class, \class{Headers}, for convenient
|
||||
manipulation of WSGI response headers using a mapping-like interface.
|
||||
|
||||
\begin{classdesc}{Headers}{headers}
|
||||
Create a mapping-like object wrapping \var{headers}, which must be a
|
||||
list of header name/value tuples as described in \pep{333}. Any changes
|
||||
made to the new \class{Headers} object will directly update the
|
||||
\var{headers} list it was created with.
|
||||
|
||||
\class{Headers} objects support typical mapping operations including
|
||||
\method{__getitem__}, \method{get}, \method{__setitem__},
|
||||
\method{setdefault}, \method{__delitem__}, \method{__contains__} and
|
||||
\method{has_key}. For each of these methods, the key is the header name
|
||||
(treated case-insensitively), and the value is the first value
|
||||
associated with that header name. Setting a header deletes any existing
|
||||
values for that header, then adds a new value at the end of the wrapped
|
||||
header list. Headers' existing order is generally maintained, with new
|
||||
headers added to the end of the wrapped list.
|
||||
|
||||
Unlike a dictionary, \class{Headers} objects do not raise an error when
|
||||
you try to get or delete a key that isn't in the wrapped header list.
|
||||
Getting a nonexistent header just returns \code{None}, and deleting
|
||||
a nonexistent header does nothing.
|
||||
|
||||
\class{Headers} objects also support \method{keys()}, \method{values()},
|
||||
and \method{items()} methods. The lists returned by \method{keys()}
|
||||
and \method{items()} can include the same key more than once if there
|
||||
is a multi-valued header. The \code{len()} of a \class{Headers} object
|
||||
is the same as the length of its \method{items()}, which is the same
|
||||
as the length of the wrapped header list. In fact, the \method{items()}
|
||||
method just returns a copy of the wrapped header list.
|
||||
|
||||
Calling \code{str()} on a \class{Headers} object returns a formatted
|
||||
string suitable for transmission as HTTP response headers. Each header
|
||||
is placed on a line with its value, separated by a colon and a space.
|
||||
Each line is terminated by a carriage return and line feed, and the
|
||||
string is terminated with a blank line.
|
||||
|
||||
In addition to their mapping interface and formatting features,
|
||||
\class{Headers} objects also have the following methods for querying
|
||||
and adding multi-valued headers, and for adding headers with MIME
|
||||
parameters:
|
||||
|
||||
\begin{methoddesc}{get_all}{name}
|
||||
Return a list of all the values for the named header.
|
||||
|
||||
The returned list will be sorted in the order they appeared in the
|
||||
original header list or were added to this instance, and may contain
|
||||
duplicates. Any fields deleted and re-inserted are always appended to
|
||||
the header list. If no fields exist with the given name, returns an
|
||||
empty list.
|
||||
\end{methoddesc}
|
||||
|
||||
|
||||
\begin{methoddesc}{add_header}{name, value, **_params}
|
||||
Add a (possibly multi-valued) header, with optional MIME parameters
|
||||
specified via keyword arguments.
|
||||
|
||||
\var{name} is the header field to add. Keyword arguments can be used to
|
||||
set MIME parameters for the header field. Each parameter must be a
|
||||
string or \code{None}. Underscores in parameter names are converted to
|
||||
dashes, since dashes are illegal in Python identifiers, but many MIME
|
||||
parameter names include dashes. If the parameter value is a string, it
|
||||
is added to the header value parameters in the form \code{name="value"}.
|
||||
If it is \code{None}, only the parameter name is added. (This is used
|
||||
for MIME parameters without a value.) Example usage:
|
||||
|
||||
\begin{verbatim}
|
||||
h.add_header('content-disposition', 'attachment', filename='bud.gif')
|
||||
\end{verbatim}
|
||||
|
||||
The above will add a header that looks like this:
|
||||
|
||||
\begin{verbatim}
|
||||
Content-Disposition: attachment; filename="bud.gif"
|
||||
\end{verbatim}
|
||||
\end{methoddesc}
|
||||
\end{classdesc}
|
||||

||||
\subsection{\module{wsgiref.simple_server} -- a simple WSGI HTTP server}
|
||||
\declaremodule[wsgiref.simpleserver]{}{wsgiref.simple_server}
|
||||
|
||||
This module implements a simple HTTP server (based on
|
||||
\module{BaseHTTPServer}) that serves WSGI applications. Each server
|
||||
instance serves a single WSGI application on a given host and port. If
|
||||
you want to serve multiple applications on a single host and port, you
|
||||
should create a WSGI application that parses \code{PATH_INFO} to select
|
||||
which application to invoke for each request. (E.g., using the
|
||||
\function{shift_path_info()} function from \module{wsgiref.util}.)
|
||||
|
||||
|
||||
\begin{funcdesc}{make_server}{host, port, app
|
||||
\optional{, server_class=\class{WSGIServer} \optional{,
|
||||
handler_class=\class{WSGIRequestHandler}}}}
|
||||
Create a new WSGI server listening on \var{host} and \var{port},
|
||||
accepting connections for \var{app}. The return value is an instance of
|
||||
the supplied \var{server_class}, and will process requests using the
|
||||
specified \var{handler_class}. \var{app} must be a WSGI application
|
||||
object, as defined by \pep{333}.
|
||||
|
||||
Example usage:
|
||||
\begin{verbatim}from wsgiref.simple_server import make_server, demo_app
|
||||
|
||||
httpd = make_server('', 8000, demo_app)
|
||||
print "Serving HTTP on port 8000..."
|
||||
|
||||
# Respond to requests until process is killed
|
||||
httpd.serve_forever()
|
||||
|
||||
# Alternative: serve one request, then exit
|
||||
##httpd.handle_request()
|
||||
\end{verbatim}
|
||||
|
||||
\end{funcdesc}
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
|
||||
\begin{funcdesc}{demo_app}{environ, start_response}
|
||||
This function is a small but complete WSGI application that
|
||||
returns a text page containing the message ``Hello world!''
|
||||
and a list of the key/value pairs provided in the
|
||||
\var{environ} parameter. It's useful for verifying that a WSGI server
|
||||
(such as \module{wsgiref.simple_server}) is able to run a simple WSGI
|
||||
application correctly.
|
||||
\end{funcdesc}

\begin{classdesc}{WSGIServer}{server_address, RequestHandlerClass}
|
||||
Create a \class{WSGIServer} instance. \var{server_address} should be
|
||||
a \code{(host,port)} tuple, and \var{RequestHandlerClass} should be
|
||||
the subclass of \class{BaseHTTPServer.BaseHTTPRequestHandler} that will
|
||||
be used to process requests.
|
||||
|
||||
You do not normally need to call this constructor, as the
|
||||
\function{make_server()} function can handle all the details for you.
|
||||
|
||||
\class{WSGIServer} is a subclass
|
||||
of \class{BaseHTTPServer.HTTPServer}, so all of its methods (such as
|
||||
\method{serve_forever()} and \method{handle_request()}) are available.
|
||||
\class{WSGIServer} also provides these WSGI-specific methods:
|
||||
|
||||
\begin{methoddesc}{set_app}{application}
|
||||
Sets the callable \var{application} as the WSGI application that will
|
||||
receive requests.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{get_app}{}
|
||||
Returns the currently-set application callable.
|
||||
\end{methoddesc}
|
||||
|
||||
Normally, however, you do not need to use these additional methods, as
|
||||
\method{set_app()} is normally called by \function{make_server()}, and
|
||||
the \method{get_app()} exists mainly for the benefit of request handler
|
||||
instances.
|
||||
\end{classdesc}
|
||||
|
||||
|
||||
|
||||
\begin{classdesc}{WSGIRequestHandler}{request, client_address, server}
|
||||
Create an HTTP handler for the given \var{request} (i.e. a socket),
|
||||
\var{client_address} (a \code{(\var{host},\var{port})} tuple), and
|
||||
\var{server} (\class{WSGIServer} instance).
|
||||
|
||||
You do not need to create instances of this class directly; they are
|
||||
automatically created as needed by \class{WSGIServer} objects. You
|
||||
can, however, subclass this class and supply it as a \var{handler_class}
|
||||
to the \function{make_server()} function. Some possibly relevant
|
||||
methods for overriding in subclasses:
|
||||
|
||||
\begin{methoddesc}{get_environ}{}
|
||||
Returns a dictionary containing the WSGI environment for a request. The
|
||||
default implementation copies the contents of the \class{WSGIServer}
|
||||
object's \member{base_environ} dictionary attribute and then adds
|
||||
various headers derived from the HTTP request. Each call to this method
|
||||
should return a new dictionary containing all of the relevant CGI
|
||||
environment variables as specified in \pep{333}.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{get_stderr}{}
|
||||
Return the object that should be used as the \code{wsgi.errors} stream.
|
||||
The default implementation just returns \code{sys.stderr}.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{handle}{}
|
||||
Process the HTTP request. The default implementation creates a handler
|
||||
instance using a \module{wsgiref.handlers} class to implement the actual
|
||||
WSGI application interface.
|
||||
\end{methoddesc}
|
||||
|
||||
\end{classdesc}
|
||||

\subsection{\module{wsgiref.validate} -- WSGI conformance checker}
|
||||
\declaremodule{}{wsgiref.validate}
|
||||
When creating new WSGI application objects, frameworks, servers, or
|
||||
middleware, it can be useful to validate the new code's conformance
|
||||
using \module{wsgiref.validate}. This module provides a function that
|
||||
creates WSGI application objects that validate communications between
|
||||
a WSGI server or gateway and a WSGI application object, to check both
|
||||
sides for protocol conformance.
|
||||
|
||||
Note that this utility does not guarantee complete \pep{333} compliance;
|
||||
an absence of errors from this module does not necessarily mean that
|
||||
errors do not exist. However, if this module does produce an error,
|
||||
then it is virtually certain that either the server or application is
|
||||
not 100\% compliant.
|
||||
|
||||
This module is based on the \module{paste.lint} module from Ian
|
||||
Bicking's ``Python Paste'' library.
|
||||
|
||||
\begin{funcdesc}{validator}{application}
|
||||
Wrap \var{application} and return a new WSGI application object. The
|
||||
returned application will forward all requests to the original
|
||||
\var{application}, and will check that both the \var{application} and
|
||||
the server invoking it are conforming to the WSGI specification and to
|
||||
RFC 2616.
|
||||
|
||||
Any detected nonconformance results in an \exception{AssertionError}
|
||||
being raised; note, however, that how these errors are handled is
|
||||
server-dependent. For example, \module{wsgiref.simple_server} and other
|
||||
servers based on \module{wsgiref.handlers} (that don't override the
|
||||
error handling methods to do something else) will simply output a
|
||||
message that an error has occurred, and dump the traceback to
|
||||
\code{sys.stderr} or some other error stream.
|
||||
|
||||
This wrapper may also generate output using the \module{warnings} module
|
||||
to indicate behaviors that are questionable but which may not actually
|
||||
be prohibited by \pep{333}. Unless they are suppressed using Python
|
||||
command-line options or the \module{warnings} API, any such warnings
|
||||
will be written to \code{sys.stderr} (\emph{not} \code{wsgi.errors},
|
||||
unless they happen to be the same object).
|
||||
\end{funcdesc}
|
||||
|
||||
\subsection{\module{wsgiref.handlers} -- server/gateway base classes}
|
||||
\declaremodule{}{wsgiref.handlers}
|
||||
|
||||
This module provides base handler classes for implementing WSGI servers
|
||||
and gateways. These base classes handle most of the work of
|
||||
communicating with a WSGI application, as long as they are given a
|
||||
CGI-like environment, along with input, output, and error streams.
|
||||
|
||||
|
||||
\begin{classdesc}{CGIHandler}{}
|
||||
CGI-based invocation via \code{sys.stdin}, \code{sys.stdout},
|
||||
\code{sys.stderr} and \code{os.environ}. This is useful when you have
|
||||
a WSGI application and want to run it as a CGI script. Simply invoke
|
||||
\code{CGIHandler().run(app)}, where \code{app} is the WSGI application
|
||||
object you wish to invoke.
|
||||
|
||||
This class is a subclass of \class{BaseCGIHandler} that sets
|
||||
\code{wsgi.run_once} to true, \code{wsgi.multithread} to false, and
|
||||
\code{wsgi.multiprocess} to true, and always uses \module{sys} and
|
||||
\module{os} to obtain the necessary CGI streams and environment.
|
||||
\end{classdesc}
|
||||
|
||||
|
||||
\begin{classdesc}{BaseCGIHandler}{stdin, stdout, stderr, environ
|
||||
\optional{, multithread=True \optional{, multiprocess=False}}}
|
||||
|
||||
Similar to \class{CGIHandler}, but instead of using the \module{sys} and
|
||||
\module{os} modules, the CGI environment and I/O streams are specified
|
||||
explicitly. The \var{multithread} and \var{multiprocess} values are
|
||||
used to set the \code{wsgi.multithread} and \code{wsgi.multiprocess}
|
||||
flags for any applications run by the handler instance.
|
||||
|
||||
This class is a subclass of \class{SimpleHandler} intended for use with
|
||||
software other than HTTP ``origin servers''. If you are writing a
|
||||
gateway protocol implementation (such as CGI, FastCGI, SCGI, etc.) that
|
||||
uses a \code{Status:} header to send an HTTP status, you probably want
|
||||
to subclass this instead of \class{SimpleHandler}.
|
||||
\end{classdesc}
|
||||
|
||||
|
||||
|
||||
\begin{classdesc}{SimpleHandler}{stdin, stdout, stderr, environ
|
||||
\optional{,multithread=True \optional{, multiprocess=False}}}
|
||||
|
||||
Similar to \class{BaseCGIHandler}, but designed for use with HTTP origin
|
||||
servers. If you are writing an HTTP server implementation, you will
|
||||
probably want to subclass this instead of \class{BaseCGIHandler}
|
||||
|
||||
This class is a subclass of \class{BaseHandler}. It overrides the
|
||||
\method{__init__()}, \method{get_stdin()}, \method{get_stderr()},
|
||||
\method{add_cgi_vars()}, \method{_write()}, and \method{_flush()}
|
||||
methods to support explicitly setting the environment and streams via
|
||||
the constructor. The supplied environment and streams are stored in
|
||||
the \member{stdin}, \member{stdout}, \member{stderr}, and
|
||||
\member{environ} attributes.
|
||||
\end{classdesc}
|
||||
|
||||
\begin{classdesc}{BaseHandler}{}
|
||||
This is an abstract base class for running WSGI applications. Each
|
||||
instance will handle a single HTTP request, although in principle you
|
||||
could create a subclass that was reusable for multiple requests.
|
||||
|
||||
\class{BaseHandler} instances have only one method intended for external
|
||||
use:
|
||||
|
||||
\begin{methoddesc}{run}{app}
|
||||
Run the specified WSGI application, \var{app}.
|
||||
\end{methoddesc}
|
||||
|
||||
All of the other \class{BaseHandler} methods are invoked by this method
|
||||
in the process of running the application, and thus exist primarily to
|
||||
allow customizing the process.
|
||||
|
||||
The following methods MUST be overridden in a subclass:
|
||||
|
||||
\begin{methoddesc}{_write}{data}
|
||||
Buffer the string \var{data} for transmission to the client. It's okay
|
||||
if this method actually transmits the data; \class{BaseHandler}
|
||||
just separates write and flush operations for greater efficiency
|
||||
when the underlying system actually has such a distinction.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{_flush}{}
|
||||
Force buffered data to be transmitted to the client. It's okay if this
|
||||
method is a no-op (i.e., if \method{_write()} actually sends the data).
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{get_stdin}{}
|
||||
Return an input stream object suitable for use as the \code{wsgi.input}
|
||||
of the request currently being processed.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{get_stderr}{}
|
||||
Return an output stream object suitable for use as the
|
||||
\code{wsgi.errors} of the request currently being processed.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{add_cgi_vars}{}
|
||||
Insert CGI variables for the current request into the \member{environ}
|
||||
attribute.
|
||||
\end{methoddesc}
|
||||
|
||||
Here are some other methods and attributes you may wish to override.
|
||||
This list is only a summary, however, and does not include every method
|
||||
that can be overridden. You should consult the docstrings and source
|
||||
code for additional information before attempting to create a customized
|
||||
\class{BaseHandler} subclass.

|

|
||||
Attributes and methods for customizing the WSGI environment:
|
||||
|
||||
\begin{memberdesc}{wsgi_multithread}
|
||||
The value to be used for the \code{wsgi.multithread} environment
|
||||
variable. It defaults to true in \class{BaseHandler}, but may have
|
||||
a different default (or be set by the constructor) in the other
|
||||
subclasses.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{memberdesc}{wsgi_multiprocess}
|
||||
The value to be used for the \code{wsgi.multiprocess} environment
|
||||
variable. It defaults to true in \class{BaseHandler}, but may have
|
||||
a different default (or be set by the constructor) in the other
|
||||
subclasses.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{memberdesc}{wsgi_run_once}
|
||||
The value to be used for the \code{wsgi.run_once} environment
|
||||
variable. It defaults to false in \class{BaseHandler}, but
|
||||
\class{CGIHandler} sets it to true by default.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{memberdesc}{os_environ}
|
||||
The default environment variables to be included in every request's
|
||||
WSGI environment. By default, this is a copy of \code{os.environ} at
|
||||
the time that \module{wsgiref.handlers} was imported, but subclasses can
|
||||
either create their own at the class or instance level. Note that the
|
||||
dictionary should be considered read-only, since the default value is
|
||||
shared between multiple classes and instances.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{memberdesc}{server_software}
|
||||
If the \member{origin_server} attribute is set, this attribute's value
|
||||
is used to set the default \code{SERVER_SOFTWARE} WSGI environment
|
||||
variable, and also to set a default \code{Server:} header in HTTP
|
||||
responses. It is ignored for handlers (such as \class{BaseCGIHandler}
|
||||
and \class{CGIHandler}) that are not HTTP origin servers.
|
||||
\end{memberdesc}
|
||||
|
||||
|
||||
|
||||
\begin{methoddesc}{get_scheme}{}
|
||||
Return the URL scheme being used for the current request. The default
|
||||
implementation uses the \function{guess_scheme()} function from
|
||||
\module{wsgiref.util} to guess whether the scheme should be ``http'' or
|
||||
``https'', based on the current request's \member{environ} variables.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{methoddesc}{setup_environ}{}
|
||||
Set the \member{environ} attribute to a fully-populated WSGI
|
||||
environment. The default implementation uses all of the above methods
|
||||
and attributes, plus the \method{get_stdin()}, \method{get_stderr()},
|
||||
and \method{add_cgi_vars()} methods and the \member{wsgi_file_wrapper}
|
||||
attribute. It also inserts a \code{SERVER_SOFTWARE} key if not present,
|
||||
as long as the \member{origin_server} attribute is a true value and the
|
||||
\member{server_software} attribute is set.
|
||||
\end{methoddesc}

Methods and attributes for customizing exception handling:
|
||||
|
||||
\begin{methoddesc}{log_exception}{exc_info}
|
||||
Log the \var{exc_info} tuple in the server log. \var{exc_info} is a
|
||||
\code{(\var{type}, \var{value}, \var{traceback})} tuple. The default
|
||||
implementation simply writes the traceback to the request's
|
||||
\code{wsgi.errors} stream and flushes it. Subclasses can override this
|
||||
method to change the format or retarget the output, mail the traceback
|
||||
to an administrator, or whatever other action may be deemed suitable.
|
||||
\end{methoddesc}
|
||||
|
||||
\begin{memberdesc}{traceback_limit}
|
||||
The maximum number of frames to include in tracebacks output by the
|
||||
default \method{log_exception()} method. If \code{None}, all frames
|
||||
are included.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{methoddesc}{error_output}{environ, start_response}
|
||||
This method is a WSGI application to generate an error page for the
|
||||
user. It is only invoked if an error occurs before headers are sent
|
||||
to the client.
|
||||
|
||||
This method can access the current error information using
|
||||
\code{sys.exc_info()}, and should pass that information to
|
||||
\var{start_response} when calling it (as described in the ``Error
|
||||
Handling'' section of \pep{333}).
|
||||
|
||||
The default implementation just uses the \member{error_status},
|
||||
\member{error_headers}, and \member{error_body} attributes to generate
|
||||
an output page. Subclasses can override this to produce more dynamic
|
||||
error output.
|
||||
|
||||
Note, however, that it's not recommended from a security perspective to
|
||||
spit out diagnostics to any old user; ideally, you should have to do
|
||||
something special to enable diagnostic output, which is why the default
|
||||
implementation doesn't include any.
|
||||
\end{methoddesc}
|
||||
|
||||
|
||||
|
||||
|
||||
\begin{memberdesc}{error_status}
|
||||
The HTTP status used for error responses. This should be a status
|
||||
string as defined in \pep{333}; it defaults to a 500 code and message.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{memberdesc}{error_headers}
|
||||
The HTTP headers used for error responses. This should be a list of
|
||||
WSGI response headers (\code{(\var{name}, \var{value})} tuples), as
|
||||
described in \pep{333}. The default list just sets the content type
|
||||
to \code{text/plain}.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{memberdesc}{error_body}
|
||||
The error response body. This should be an HTTP response body string.
|
||||
It defaults to the plain text, ``A server error occurred. Please
|
||||
contact the administrator.''
|
||||

Methods and attributes for \pep{333}'s ``Optional Platform-Specific File
|
||||
Handling'' feature:
|
||||
|
||||
\begin{memberdesc}{wsgi_file_wrapper}
|

A \code{wsgi.file_wrapper} factory, or \code{None}. The default value
|
||||
of this attribute is the \class{FileWrapper} class from
|
||||
\module{wsgiref.util}.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{methoddesc}{sendfile}{}
|
||||
Override to implement platform-specific file transmission. This method
|
||||
is called only if the application's return value is an instance of
|
||||
the class specified by the \member{wsgi_file_wrapper} attribute. It
|
||||
should return a true value if it was able to successfully transmit the
|
||||
file, so that the default transmission code will not be executed.
|
||||
The default implementation of this method just returns a false value.
|
||||
\end{methoddesc}
|
||||
|
||||
|
||||
Miscellaneous methods and attributes:
|
||||
|
||||
\begin{memberdesc}{origin_server}
|
||||
This attribute should be set to a true value if the handler's
|
||||
\method{_write()} and \method{_flush()} are being used to communicate
|
||||
directly to the client, rather than via a CGI-like gateway protocol that
|
||||
wants the HTTP status in a special \code{Status:} header.
|
||||
|
||||
This attribute's default value is true in \class{BaseHandler}, but
|
||||
false in \class{BaseCGIHandler} and \class{CGIHandler}.
|
||||
\end{memberdesc}
|
||||
|
||||
\begin{memberdesc}{http_version}
|
||||
If \member{origin_server} is true, this string attribute is used to
|
||||
set the HTTP version of the response set to the client. It defaults to
|
||||
\code{"1.0"}.

|
||||
The changes in Python 2.5 are an interesting mix of language and
|
||||
library improvements. The library enhancements will be more important
|
||||
to Python's user community, I think, because several widely-useful
|
||||
packages were added. New modules include ElementTree for XML
|
||||
processing (section~\ref{module-etree}), the SQLite database module
|
||||
(section~\ref{module-sqlite}), and the \module{ctypes} module for
|
||||
calling C functions (section~\ref{module-ctypes}).
|
||||
|
||||
% XXX Compare with previous release in 2 - 3 sentences here.
|
||||
The language changes are of middling significance. Some pleasant new
|
||||
features were added, but most of them aren't features that you'll use
|
||||
every day. Conditional expressions were finally added to the language
|
||||
using a novel syntax; see section~\ref{pep-308}. The new
|
||||
'\keyword{with}' statement will make writing cleanup code easier
|
||||
(section~\ref{pep-343}). Values can now be passed into generators
|
||||
(section~\ref{pep-342}). Imports are now visible as either absolute
|
||||
or relative (section~\ref{pep-328}). Some corner cases of exception
|
||||
handling are handled better (section~\ref{pep-341}). All these
|
||||
improvements are worthwhile, but they're improvements to one specific
|
||||
language feature or another; none of them are broad modifications to
|
||||
Python's semantics.
|
||||
|
||||
This article doesn't attempt to provide a complete specification of
|
||||
the new features, but instead provides a convenient overview. For
|
||||
full details, you should refer to the documentation for Python 2.5.
|
||||
As well as the language and library additions, other improvements and
|
||||
bugfixes were made throughout the source tree. A search through the
|
||||
SVN change logs finds there were 334 patches applied and 443 bugs
|
||||
fixed between Python 2.4 and 2.5. (Both figures are likely to be
|
||||
underestimates.)
|
||||
|
||||
This article doesn't try to be a complete specification of the new
|

features; instead changes are briefly introduced using helpful

||||
examples. For full details, you should always refer to the

documentation for Python 2.5.

The \module{functools} module is intended to contain tools for

functional-style programming. Currently it only contains a

For programs written in a functional style, it can be useful to

One useful tool in this module is the \function{partial()} function.
|
||||
For programs written in a functional style, you'll sometimes want to
|
||||
construct variants of existing functions that have some of the
|
||||
parameters filled in. Consider a Python function \code{f(a, b, c)};
|
||||
you could create a new function \code{g(b, c)} that was equivalent to
|
||||
\code{f(1, b, c)}. This is called ``partial function application'',
|
||||
and is provided by the \class{partial} class in the new

Another function in the \module{functools} module is the

\function{update_wrapper(\var{wrapper}, \var{wrapped})} function that
|

helps you write well-behaved decorators. \function{update_wrapper()}
|
||||
copies the name, module, and docstring attribute to a wrapper function
|

so that tracebacks inside the wrapped function are easier to

understand. For example, you might write:

\item Evan Jones's patch to obmalloc, first described in a talk
|
||||
at PyCon DC 2005, was applied. Python 2.4 allocated small objects in
|
||||
256K-sized arenas, but never freed arenas. With this patch, Python
|
||||
will free arenas when they're empty. The net effect is that on some
|
||||
platforms, when you allocate many objects, Python's memory usage may
|
||||
actually drop when you delete them and the memory may be returned to
|
||||
the operating system. (Implemented by Evan Jones, and reworked by Tim
|
||||
Peters.)
|
||||
|
||||
Note that this change means extension modules must be more careful
|
||||
when allocating memory. Python's API has many different
|
||||
functions for allocating memory that are grouped into families. For
|
||||
example, \cfunction{PyMem_Malloc()}, \cfunction{PyMem_Realloc()}, and
|
||||
\cfunction{PyMem_Free()} are one family that allocates raw memory,
|
||||
while \cfunction{PyObject_Malloc()}, \cfunction{PyObject_Realloc()},
|
||||
and \cfunction{PyObject_Free()} are another family that's supposed to
|
||||
be used for creating Python objects.
|
||||
|
||||
Previously these different families all reduced to the platform's
|
||||
\cfunction{malloc()} and \cfunction{free()} functions. This meant
|
||||
it didn't matter if you got things wrong and allocated memory with the
|
||||
\cfunction{PyMem} function but freed it with the \cfunction{PyObject}
|
||||
function. With 2.5's changes to obmalloc, these families now do different

\section{Other Changes and Fixes \label{section-other}}
|
||||
|
||||
As usual, there were a bunch of other improvements and bugfixes
|
||||
scattered throughout the source tree. A search through the SVN change
|
||||
logs finds there were XXX patches applied and YYY bugs fixed between
|
||||
Python 2.4 and 2.5. Both figures are likely to be underestimates.
|
||||
|
||||
Some of the more notable changes are:
|
||||
|
||||
\begin{itemize}
|
||||
|
||||
\item Evan Jones's patch to obmalloc, first described in a talk
|
||||
at PyCon DC 2005, was applied. Python 2.4 allocated small objects in
|
||||
256K-sized arenas, but never freed arenas. With this patch, Python
|
||||
will free arenas when they're empty. The net effect is that on some
|
||||
platforms, when you allocate many objects, Python's memory usage may
|
||||
actually drop when you delete them, and the memory may be returned to
|
||||
the operating system. (Implemented by Evan Jones, and reworked by Tim
|
||||
Peters.)
|
||||
|
||||
Note that this change means extension modules need to be more careful
|
||||
with how they allocate memory. Python's API has many different
|
||||
functions for allocating memory that are grouped into families. For
|
||||
example, \cfunction{PyMem_Malloc()}, \cfunction{PyMem_Realloc()}, and
|
||||
\cfunction{PyMem_Free()} are one family that allocates raw memory,
|
||||
while \cfunction{PyObject_Malloc()}, \cfunction{PyObject_Realloc()},
|
||||
and \cfunction{PyObject_Free()} are another family that's supposed to
|
||||
be used for creating Python objects.
|
||||
|
||||
Previously these different families all reduced to the platform's
|
||||
\cfunction{malloc()} and \cfunction{free()} functions. This meant
|
||||
it didn't matter if you got things wrong and allocated memory with the
|
||||
\cfunction{PyMem} function but freed it with the \cfunction{PyObject}
|
||||
function. With the obmalloc change, these families now do different
|
||||
things, and mismatches will probably result in a segfault. You should
|
||||
carefully test your C extension modules with Python 2.5.
|
||||
|
||||
\item Coverity, a company that markets a source code analysis tool
|
||||
called Prevent, provided the results of their examination of the Python
|
||||
source code. The analysis found about 60 bugs that
|
||||
were quickly fixed. Many of the bugs were refcounting problems, often
|
||||
occurring in error-handling code. See
|
||||
\url{http://scan.coverity.com} for the statistics.

||||
